One of the most used commands in linux to find about the running processes in linux is ps command and top command. There are many command line arguments that we can give to these commands to extract the exact information that we need. But it is a bit confusing, right? So here we are going to look for the most used command line arguments in the ps command.

This is a basic question that arises in the mind of the most new linux users. This can be easily achieved in linux. Its a matter of just adding a do in front of the file/folder name in linux.

For example, to hide a file called 'linux-tips.txt', we just need to add a dot in front of it. It will be like this.

.linux-tips.txt

You can use the mv command to do it in command line. The above can be done like this:

mv linux-tips.txt .linux-tips.txt

Once we add the dot infront of it, it won't be visible in 'ls' command. You can view the hidden files by using 'ls -a' command.

The same method works for folders also.

So how to remove an application completely in ubuntu?
